' be polished with great ease and remarkably efficiently. The device adjusts itself in a perfect manner to the shape, curvature and convexity of the finger nail and enables all parts of the nails to be reached without the least difficulty. Devices for polishing the linger nails known hitherto have a polishing surface very hard, without any give,in such a` way that in order yto operate upon the whole convex surface of the nails, it is necessary to rub the latter for a very long time and to constantlyvary the inclination of the instrument. When the operation is carried out quickly only the middle top portion, which is the most convex, of the nail, is polished, while the lateral portions remain dull,

and this gives a careless and disagreeableappearance to the nails. Some linger nails have a curvature which is hardly at all regular, presenting rentrant parts and other parts which project more. With known instruments these nger nails can only be p'olished with very great diiiiculty.

The present invention is intended to remove these inconveniences and to provide an arrangement allowing the nails to be polished with the greatest ease and in a perfect manner. The device consists essentially in applying skin or other material intended to form a rubbing surface upon a pneumatic chamber inflated in such a manner as to stretch the skin and to give it a certain resistance, while still assuring that it remains quite supple. This pneumatic device adjusts itself and applies itself to the finger' nails in a very exact manner and shapes itself to all the shapes and all the curvatures of the latter in such a manner that it isi only necessary to rub for a few moments in order to instantly polish the whole surface of the finger nails.

The annexed drawing shows by way of example, several methods of carrying this invention into practice.

Figure l is an elevation of my invention complete with outer cover and inflation valve.

Fig. 2 is a cross section of Fig. l.

Fig. 3 is a cross section of a modification.

The device comprises essentially an exterior envelop l of chamois skin or other suitable material, which is preferably given a cylindrical shape, shown in Fig. l, by stitching or by other means. An air chamber or a bladder of india rubber 2 similar to those of pneumatic bandages or of toy balloons, is arranged in the interior of this envelop l. This chamber or bladder is inflated in the usual well known manner, preferably by means of a small ain pump, the connection of which is screwed on to the valve 3. By compressing air in the interior of the chamber or bladder 2 the exterior skin is inflated to the vdesired extent.

In order to prevent the skin l from sliding over the chamber or;'bladder 2 during polishing the finger nail, swellings or ribs may be formed on the interior surface of the skin 1 for maintaining the chamber or bladder 2 in position.

In order to give the arrangement a certain rigidity in the longitudinal direction it may be divided internally by a partition 5 of flexible metal, leather, and so forth (Fig. 2.) In this case there is an air chamber or bladder 2 upon each side of this partition. The two chambers or bladders can be connected at one of the ends and be connected to a common valve.

The same rigidity can also be obtained by means of a frame of metallic wire or other material 6, preferably having a section of an inverted channel (Fig. 3). It should be understood that other shapes and other methods of construction may be employed. The details of construction can even be modified. Moreover, the different constituent elements of this invention can be replaced by others playing the same part and giving the same result.

What I claim is A flexible hand-polisher for treating the finger-nails, capable of beingvfolded, of inflation and deflation, and of being rolled up for packing, comprising in combination an outer envelop presenting polishing surfaces, this specification in the presence of two suban impervious air chamber, a valve Contiol- Sci'ibing Witnesses.
